What it does
Provides a comprehensive framework for developing an SEO strategy, covering core principles, a maturity model, technical SEO (crawlability, indexability, sitemaps, robots.txt, Core Web Vitals, structured data), content SEO (keyword research, content clusters, topic authority, E-E-A-T), on-page elements (title tags, meta descriptions, header tags, internal linking), and off-page SEO (backlinks). It also includes practical examples, checklists, and code blocks for crawl budget prioritization and keyword priority scoring.
How it works
- Outlines core principles that SEO should serve user intent, emphasize content quality, and rely on data-driven decisions.
- Defines a SEO Maturity Model with Levels L1–L5 and progression steps (e.g., analytics installation, rank tracking, structured content, pillar clusters, automation).
- Details Technical SEO procedures:
- Crawlability: prioritization schema for crawl budget (high/medium/low/noindex) and common blockers.
- Indexability: checklist ensuring HTTP 200, crawlable URLs, indexable content, no problematic canonical or paywalls.
- XML Sitemaps: formatting example, submission guidance, limits, and dynamic sitemaps.
- Robots.txt: example directives and common mistakes.
- Core Web Vitals: targets and optimization tactics for LCP, INP/FID, CLS.
- Structured Data: sample JSON-LD and priority schemas, plus testing tools.
- Covers Content SEO:
- Keyword Research process with seed list, expansion tools, intent categorization, prioritization formula (priority_score function).
- Content Clusters and Pillar/cluster structure with roles and word counts.
- Topic Authority framework and E-E-A-T components with actions to demonstrate expertise and trust.
- Describes On-Page SEO:
- Title Tags: formula, best practices, examples.
- Meta Descriptions: length and content guidance.
- Header Tags: H1/H2/H3 usage rules and example structure.
- Internal Linking: best practices, anchor text examples.
- Addresses Off-Page SEO:
- Backlinks overview and emphasis on quality, with factors like authority noted (text truncated in provided content).
When to use it
- Use when planning or auditing an SEO program from scratch or during a maturity upgrade, to align on technical foundations, content strategy, and measurement.
What it can touch
- Tools declared: claude-code. It includes Python-like code blocks for crawl budget prioritization and keyword priority scoring, which the agent can interpret and execute within its environment.
Caveats
- Content includes illustrative code blocks and examples; actual implementation should adapt to site specifics and current search engine guidance. Some sections reference general best practices and thresholds (e.g., Core Web Vitals targets) that should be validated against up-to-date metrics and platform capabilities.
# SEO Strategy ## Core Principles ### 1. Search Engines Want What Users Want Google's mission is to organize the world's information and make it universally accessible. Every algorithm update rewards content and technical setups that serve user intent. SEO is not about "gaming the system" — it is about making your site the best answer to a searcher's question. ### 2. Content is the Foundation, Not an Add-On No amount of technical optimization can save thin, irrelevant, or unhelpful content. SEO begins with understanding what your audience searches for and creating resources that genuinely satisfy that need. Technical SEO opens the door; content quality earns the ranking. ### 3. Authority is Earned, Not Built Search engines evaluate authority through signals like backlinks, brand mentions, E-E-A-T signals, and user engagement metrics. You cannot buy authority or shortcut it with spammy tactics. Consistent value delivery over time is the only durable path. ### 4. Technical Health is Table Stakes If search engines cannot crawl, render, and index your pages, your content quality is irrelevant. Technical SEO is not optional — it is the prerequisite for every other effort. Core Web Vital

How do I install it?
Run `npx skills add cosmicstack-labs/mercury-agent-skills --skill seo-strategy --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From cosmicstack-labs/mercury-agent-skills, a repository with 364 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
